Given that,
y varies directly with x and y = 10 when x = 20.
To find,
The value of y when x = 15.
Solution,
![y\propto x\\\\y=kx](https://tex.z-dn.net/?f=y%5Cpropto%20x%5C%5C%5C%5Cy%3Dkx)
Put x = 20 and y = 10
![k=\dfrac{y}{x}\\\\k=\dfrac{10}{20}\\\\=\dfrac{1}{2}](https://tex.z-dn.net/?f=k%3D%5Cdfrac%7By%7D%7Bx%7D%5C%5C%5C%5Ck%3D%5Cdfrac%7B10%7D%7B20%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B2%7D)
Put k = 1/2 and x = 15 to find the value of y.
![y=\dfrac{1}{2}\times 15\\\\=7.5](https://tex.z-dn.net/?f=y%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%2015%5C%5C%5C%5C%3D7.5)
So, the value of y is 7.5

Answer:
If my friend is in 5th grade and they need an example on exponents I would show them something like this 7 to the 3 power would be equal to 7 times 7 times 7 which also equals 343 or 4 to the 4th power would be equal to 4 times 4 times 4 times 4 which equals 256
